FIRST RECORD OF Chersotis rectangula ([Denis & Schiffermüller], 1775) IN CROATIA WITH NEW DATA FOR Chersotis Multangula (Hübner, 1803) (Lepidoptera: Noctuidae)
PRVI NALAZ Chersotis rectangula ([Denis & Schiffermüller], 1775) ZA HRVATSKU I NOVI PODACI O Chersotis Multangula (Hübner, 1803) (Lepidoptera: Noctuidae)
Toni KOREN, Stanislav GOMBOC
During the moth survey of the hills Straninjščica and Ivanščica in the Krapina-Zagorje County in Croatia in 2014, many interesting moth species were recorded. Among them, the noctuid Chersotis rectangula ([Denis & Schiffermüller], 1775), new for Croatian fauna. Three specimens of Ch. rectangula were collected on the UV light traps at the top of Ivanščica Mt., on 8 June 2014. This is the sixth species of the genus Chersotis occurring in Croatia. Other species are Ch. multangula (Hübner, 1803), Ch. margaritacea (Villers, 1789), Ch. elegans (Eversmann, 1837), Ch. fimbriola (Esper, 1803) and Ch. cuprea (Denis & Schiffermüller, 1775). Aside from Ch. rectangula, Ch. multangula was also recorded in the same season on Straninščica and Ivanščica Mts., which is the north-easternmost occurrence of this species for the country.

Of the most numerous moth families in Croatia (e.g. Erebiidae, Crambidae, Geometridae, Noctuidae, Pyralidae, Tortricidae), the Noctuidae are by far the best studied family. This is mostly due to several larger previous surveys in various parts of Croatia: Krk Island (Habeler 2003), Kupa River (Mladinov 1977), Gorski Kotar (Kučinić et al. 1993), north-western Croatia (Kučinić & Bregović 1996), Podravina (Kranjčev 1984), Kopački Rit (Vignjević et al. 2010), reviews of the data from museum collections (Mladinov 1958; Kučinić & Hrašovec 1999), as well as contributions of several new species records for the country (Kučinić & Perović 1997; Kučinić et al. 1998; Kučinić & Lorković 1999). Except these contributions, the noctuid fauna of Croatia remains poorly known, since most of the studies were concentrated on a very small area and were not systematic surveys. The northern part of the country is the least studied region.
The genus Chersotis Boisduval, 1840 consists of 76 species, of which 20 can be found in Europe (Fibiger & Hacker 1990; Fibiger 1993; Witt & Ronkay 2011; Fibiger & Skule 2013; Varga et al 2013). They are usually connected to
